Answer:
We know that, a³ - b³ = (a - b)(a² + ab + b²)
Now,
- x³ - 27
- (x)³ - (3)³
- (x - 3)(x² + 3x + 9)
Therefore,
- <u>(x² + 3x + 9)</u> is the other factor.
Answer: 75 is a composite number. 75 = 1 x 75, 3 x 25, or 5 x 15. Factors of 75: 1, 3, 5, 15, 25, 75. Prime factorization: 75 = 3 x 5 x 5, which can also be written 75 = 3 x 5².
To find<span> the perimeter of the </span>quarter circle<span>, </span>find<span> the circumference of the whole </span>circle<span>, divide by 4, and then add the radius twice.
